ways some remains on the ground. This F crass or hav lvine in bushels for bulksris not i* 1 .d P .i thoroughly aired and dried up and o'l'ien causes moulding in the hay stock, which often is the rea-son of hay stock lirebrands. Fur thermore unequally dried grass or hay yields bad fodder' and causes disordersof the stomach-and the intestines vand bad qualities of the milk. l

The purpose of the presentinvention is to overcome these disadvantages and it consist-s from the ground thoroughly` Vstirring and finally in scattering and throwing it out so that it falls down equally distributed. The machine affords considerable vreduction of working time.

For this purpose the machine comprises a mainframe supportedrby'two wheels, a second frame pivotally mounted on the first frame, a pronged roller rotatably mounted at the front end of the second frame, an endless conveyor passing over av driving'rollery and two guide rollers supported by thesecond frame for receiving andy conveying backward the hay scattered and tal-ien up bythe said pronged roller, levers supported by theV second frame andv carrying stirring membersk adapted to stir the hay on the conveyor, a rake adjustably supported by the second frame and adapted toV uniformly distribute the hay, a pronged drum rotatably mountedat the rear end of thesecond frame 'and adapted to throw out the hay distributed on the conveyer, means for rotatingr thefront for rotating the rear pronged drum from the in first taking up all the cut grass or hay y'to convey the hay.

prongedroller from the said wheels, meansv Fig. 4 represents a vertical section on line E-F in Fig. 1.

Similar letters of reference indicate similar parts throughout the several views.

Referring to theV4 drawing 1 indicates a frame having front wheels 2, back wheels 3', a seat 4 for the driver `and an enchasing 'device for the horse. Of course the frame also may be drivenl by amotor. The shaft G'to which the wheels 2 are fixed is j ournaled in theframc 1 whilea coupling shaft 7 is jour j naled inv apivotable frame 10 Vbeneath the wheel shaft' 6.- A toothed wheel 8 is fiXedly mounted on the shaft 6 which meshes with a toothed wheel 9 fixed to theV eouplingshaft 7.- The frame 10 is pivotally supported by the shaft 6 and `three drums 11, 12 and 413 are journaled in the frainevlO over which drums l runs an endlessconveyer band 15 providedA f with prongs'lll." A sprocket 161s rigidly mounted on'the c'oiuoling` shaft 7 and connected by a Vchain 1T to another sprocket 1S fixed to the shaft of the drinn 13. Thereby the drum 13 is driven in such a way that the upper or working drum of the band lvmoves from theV front tofthe back ofthe machine Tension is imparted to the conveying` band `15" and lcontrolled rby means'of springs QGp'lacedin the forks of brackets 25 and acting` upon thepivot-journals 24; of the axle 23 of the upper guide drum 12. The forked brackets 25are supported by supports Q of the swinging Aframe 10.

A pronged roller 19 is jonrnaled in the front end of the frame 1() and driven from the. shaft of the front drum 11 by means of sprockets QOgandQQ and a chain 21.

A further sprocket 2T is' rigidly, mounted to the :coupling shaft 7 which by means of a chain 28 and a sprocket 29 drives ashaft 30 f on which a cani-roller 511` (described later)` carrying a pulley31 is keyed. 'An endless rope 32 connects the pulley 31 to a pulley fixed to a broken shaft 36 the parts A'of which are connected by universal joints 37. The

yshaft isjournaled 'inV brackets having balljournals 34 and in adjustable ball-bearings 35 receiving the'outer ends of the said shaft." A'pronged drum 38 isarranged between each universal joint 37 and an outer' bearing -35 and consists ot two end discs connected by pronged bars. The outer ball-bearings are adjustable in slots converging to the front of the machine and provided in supports 39 fixed to the pivotable frame 10. Thus the rear drums 38 are capable to form an adjustable obtuse angle, as shown by Fig. 2; from this angle depends the lateral scattering extent. Lateral guards 41 secured to the pivotable frame 10 prevent the hay on the conveyor from laterally falling off. The gears, sprockets and chains preferably are housed in suitable casings not shown. lVhen the machine has to run without working, the front of the pivotable traine 1() and the iront pronged roller 19 have to bc lifted. This will be performed by the following means:

A shaft 43 is journaled in brackets 42 fixed to the main 'rame 1 and rigidly carries two arms 44. To each ot these arms a rod 45 loosely supporting the pivotablc trame 10 is suspended. A spring 450 inserted between a collar of each rod 45 and the frame 10 acts as a buffer to receive the stocks of the frame 10 when the' machine passes Yover uneven ground. A hand lever 440 is fixed to the shaft 43 and so arranged that it can easily be operated by the driver to lift or to lower the pivotable frame 10 as will be necessary.

As formerly described, a cam-roller 54 is secured to the shaft 30 journaled in brackets 46 of the supports 270. Two levers 48 are pivoted to a cross-bar 47 supported by the pivotable frame 10. The front ends otl these levers are provided with rollers (not shown) and enter into the grooves of the cam-roller 54 whereby oscillations can be imparted to the said levers. The rear ends of the levers 48 have vertical guides to which forks 49 (see Figs. 1 and 4) are adjustably secured by means of thumb screws. Each fork has for its purpose to stir the hay thrown upon the Y conveyer 15 by the front pronged roller 19. Thereby each fork-prong only works in one direction and yields in the other. l

Pillars 51 are iiXed to the supports 39 and a horizontal rake is adjustably mounted on these pillars. The rake is adapted to control the passage of the hay to the scattering drums 38 and to prevent forming of heaps ot' hay on the conveyer.

52 is a coupling member slidable on the coupling shaft 7 but rigidly ixed to it in the sense of rotation. This member can be engaged with another coupling member 53 connected tothe sprocket 16 by the following means: A handle 55 is `journaled in a bracket 56 fixed to the main frame 1 and has a tubular lower end in which a rod 57 loosely connected to the coupling lever 58 is movable.l The lever 58 is pivotally mounted to a pivot 59 of the pivotable frame 10 and engages with its forkedk end an annular groove of the coupling member 52 to move it in and out of driving connection with the other coupling member 53. lVhcn the machine runs over unevennesses of the ground the rod 57 slides in the tubular end of the handle 55 so that no prongs ot the pronged roller 19 will be injured. The handle may be secured in position in usual manner by means of a blocking rod engaging a toothed segment fixed to the bracket 56.

The operation ot' the machine as described is as follows:

The machine is moved along a meadow and the conveyer band 15 is brought in continuons circulation in the direction of the arrow lD by the different gears and sprockets driven by the running wheels The front pronged roller 19 is rotated with highl speed in the direction of the arrow Q and the rear drums 38 are rotated in the direction ot the arrow R. The prongs of the roller 19 in taking up the hay scatter it and throw it without leaving behind a remainder on the ground upon the conveyer band 15. This carries the hay to the forks 49 of the levers 48 which stir the hay upon the conveyer. The rake 50 controls the passage of the hay to the rear scattering or throwing out drums 38 in such a way that hay it too much is dcposited on the conveyer in some place will be retained and thereupon delivered to places to which less hay has been deposited by the forks 49. The pronged drums 38 throw out backwards the regularly distributed hay. Proportionally to the mutual angular adjustment of the two rear drums 38, the scattering extent is greater or less, the extent being the greater the less the said angle is.

lVhen no further work of the machine is desired, the coupling 52, 53 is disengaged and the front part of the movable frame is lifted. Only a single scattering drum 38 parallel to the rake 50 may be used instead of two.

What I claim is 1. In a machine of the class described, the combination with driving wheels, oi an endless conveyer, gearing for transmitting motion from the driving wheels to the endless conveyer, a pronged roller rotatably journaled in front of the endless conveyer to take up the hay and throw it upon the conveyer, gearing for transmitting motion from the driving wheels to the said pronged roller, stirring members adapted to stir the hay carried by the conveyer, gearing for trans.- mitting motion from the driving wheels to the stirring members, a bi-parted pronged drum rotatably mounted over the rear end ot the convcyer to throw out the hay carried by the conveyer, the two parts of the said drum being angularly adjustable one to t-he other to control the scattering extent of the drum, and gearing for transmitting motion from the driving wheels to the pronged drums.
